Jon I think you have two IACs with blown coils. According to the FSM, looking at the connector-side of the IAC you will see six pins:

1 2 3
4 5 6

Measure the resistance between 1-2 and 2-3. Spec is 28-33 ohms.

Measure the resistance between 4-5 and 5-6. Spec is 28-33 ohms.

I think most IACs you'll get from the junkyard are going to be DOA. You can get a brand new one from dsmisc.com for less than $150. That's what I did when suddenly the idle would no longer bump up when the A/C came on. Popped the new one in, works like a champ.

Good luck! <img src="/forums/images/graemlins/kewl.gif" alt="" />
